WILLIAM MELVILLE, or MANIGHESTEKQENGLAND SUBSTITUTE FOR OIL- CLOTH OR LINOLEUIV}.

' body of the new material fibrous-pulp paper made from textile material of commercially known as backing, which is and is close-grained and tough. This material in any suitable length, width, and thickness I treat with a filling and stifiening substanceco'nsisting of an emulsion of oil, water, size, lime, and soda,- the emulsion being prepared in the following manner, viz: In a mixer, such as is commonly used for mixing colors, the oil and water are placed along with the size. The stirrer is then set in motion, and while the ingredients are being mixed the soda and lime are added until a cream-like emulsion is produced. ,For oils with little grease in them the lime may be omitted.

The manner of treating the material is as follows: The emulsion is placed ready made in a large vat, in the lower part of which are three rollers, one near each bottom corner and one in the center. Above one edge of the vat is a pair of rollers, and above the.

other edge is a carrier-roller. The. end of the material to be treated is led over this lastnamed roller, then down and through the liquid in the vat, passing under and over the passing between the two rollers on the other side of the vat. These latter, being driven by gearing, pull the material through the liquid, the rate of traverse being such as to insure the thorough saturation of the'material.

After leaving the vat-the material passes over drying-cylinders or is festooned and allowed to ban in a heated room until dry, or it goes after an extended traverse to the forwar next treatment. This latter consists in coating the material back-and front or front only with oils andstaining colors of the re uired shade. After drying and if a plain ma erial ng staple,

is required the material is ready for use. If,

however, a pattern is required, the material is then printedwith the desired pattern in like manner to ordinary oil-cloth.

The proportions of the ingredients which I have successfully employed in my experiments are as follows, in one hundred parts, by

weight: oil', (preferably linseed,-) sixty-seven parts; water, twenty-five parts; size, (gela-w tin glue or the like,) five parts; soda,'(sodium carbonate,) one and one-half parts;

lime, (calcium oxid,) one andone-half parts;

The object and effect of passing the material through the oil emulsion are to fill all the pores or interstices of the material, and thus render it non-absorbent, and thus incapable of absorbing the subsequent coatings of oil-colors, for without such treatment the colors would sink in and become dead, whereas with the material prepared as aforesaid they remain on the surface and give as good an effeet as printed linoleum.

With a closely-grained material the filllng liquid requires to be somewhat of thin consistency but for anopen-grained material it will require to be of thicker consistency, more water being used and less oil, or vice versa, according to'the readiness with which the material absorbs the emulsion, The soda and lime are varied to suit the readiness of the water and oil to mix and with the greasi; ness of the oil; but the proportions efore named will usually serve. While preferring fibrous pa er afterthe paper 1s made, it may be applie during the course of its manufacturethat is to say, whi e in a state of pulp-r the pulp and the fillin material being well mixed prior-to the pulp passing to the paper-- making machine.'

rollers at the bottom of the vat, and then cloth and linoleum consisting of fibrous-pulp 'to apply the said filling preparation to the paper, impregnated with an emulsified filling of oil, water and size, and after impre a' tion printed with ordinary oils and co ors, substantially as set forth.

In witness whereof ,I have hereunto set my hand in the presence offtwo' witnesses.
